摘要： An image-forming machine has a sheet member conveying passage extending through a transfer zone and a fixing zone, a sheet member-feeder for feeding a sheet member to the sheet member conveying passage, and a sheet member conveyor for conveying the sheet member through the sheet member conveying passage. A housing of the image-forming machine has a lower surface defined by an intermediate lower wall and an upper surface defined by an intermediate upper wall, and has a space of which the front surface is opened. The downstream end portion of the sheet member conveying passage extends along one side portion of the intermediate lower wall on the lower side thereof. That one side portion of the intermediate lower wall is defined by an opening/closing member which is brought to the open position to open the downstream end portion of the sheet member conveying passage. The sheet member conveyer includes a pair of register rollers. After the leading edge of the sheet member delivered to the sheet member conveying passage is brought into contact with the nip of the pair of register rollers, the pair of register rollers are preliminarily rotated for only a predetermined period of time.

摘要： An imaging unit includes a developer unit which is supported rotatably about a predetermined rotation axis thereof by means of a drum unit. Spacing regulation sleeves are respectively fitted around opposite ends of a support shaft of a developer roller for regulating a spacing between the photoreceptor drum and the developer roller. A driven gear is engaged with one end of the support shaft of the developer roller for integral rotation thereof, and adapted to be driven by a drive transmission gear. By utilizing a driving force applied to the driven gear, the developer unit is biased about the rotation axis to press one spacing regulation sleeve fitted around one end of the support shaft of the developer roller against the photoreceptor drum. The other spacing regulation sleeve fitted around the other end of the support shaft of the developer roller is resiliently pressed against the photoreceptor drum by means of a resilient member.

摘要： A device for developing an electrostatic latent image including a developing housing having a developing chamber, a stirrer chamber, and a developing agent-feeding port communicating with the stirrer chamber. A developing roller is disposed in the developing chamber to hold, on the peripheral surface thereof, a developing agent in a developing agent-holding zone, and convey the thus held developing agent to a developing zone to apply it to the electrostatic latent image. A replenishing device feeds the developing agent onto the peripheral surface of the developing roller in the developing agent-holding zone. A stirring device disposed in the stirrer chamber stirs the developing agent that is fed through the developing agent-feeding port and sends the stirred developing agent to the developing chamber. A vibration plate having a plurality of developing agent-flow ports is disposed at the developing agent-feeding port of the developing housing, and the stirring device is caused to act on the vibration plate.

摘要： A developing unit has a voltage-applicator (80) to apply a developing bias voltage to a developing roller (72). The voltage-applicator (80) applies the developing bias voltage for a first duration to apply an AC voltage having a rectangular waveform, and a second duration to stop applying the AC voltage. The AC voltage has a duty ratio of 50% or more in a direction for causing toner to develop an electrostatic latent image. The number of cycles of the AC voltage in the first duration is two or more, and the AC voltage has a voltage in a direction for pulling the toner back to the developing roller, just before transition to the second duration. The developing unit suppresses occurrence of image unevenness due to a fluctuation in developing gap. Thus, an image forming apparatus equipped with the developing unit forms a high-quality image while suppressing image unevenness.
